COTTON-SHOPPER.

Specification ei' Letters Patent.

Patented Aug. 2e, 190e.

Application filed January 31) 190B. Serial No. 298.835.

T0 all whom it may concern:

Be it known that I, JOHN N. KEATHLEY, a citizen of the United States,residing at Elmore, in District No. 17 of Indian Territory, haveinvented certain new and useful Imrovements in Cotton-Choppers, of whichthe fbllowing is a s ecification.

The object o my invention is to provide certain new and useful imrovements in cotton-choppers, which will e hereinafter described, andspecifically pointed out in the appended claims.

For a full description of the invention and the merits thereof and alsoto acquire a knowledge of the details of construction of the means foreffecting the result reference is to be had to the following descriptionand accompanying drawings, in which Figure 1 is a perspective view of myiinproved cotton-chopper. Fig. 2 is a side elcvation thereof. Fig. 3 isa top plan view. Fig. 4 is a transverse sectional view.

Corresponding and like parts are referred to in the followin descriptionand indicated in all the views o the drawings by the same referencecharacters.

Referring to the drawings, the numeral 1 designates the main frame of myimproved cotton-chopper, which is mounted upon a transverse axle 2,supported by traveling wheels 3, provided with tractor surfaces oreriph'eries to prevent sli ping. The main ame 1 has secured to its rontend a ole or tonfrue 4, and to its rear end is secure a vertically andrearwardly extending spring-bar 5, supporting the drivers seat G at itsupper end.

Mounted upon the transverse beam 1 of the frame is an upright post orstandard 7, and a similar post or standard 8 is mounted upon the rearcross-bar of the frame 1. A longitudinallyextending lever 9 is fulcrnmedintermediate of its ends on the post 7 and is provided at its rear endwith a handle 10, by which it may be rocked. The post or standard 8 isprovided with teeth or notches S, with which the rear end of the lever 9is intended to be engaged, so as to hold the lever in different angularpositions. To the front end of the lever 9 there is secured a dependingarm 11., to the lower end of which is secured a beam 12. .lo cach end.of the beam 12 is connected a yoke 13, the oppositely-extending arms ofwhich are secured to and support the inner auxiliary frame 14. Theextremities of the yoles 13 pass through eyes or similar guides 15 onthe main framework and are guided. thereby. As the lever El) is rockedso as to elevate or depress its front end it is evident that the innerframe 14 will be raised or lowered.

In the inner frame 14 there is journaled a longitudinally-extendiiigshaft 16, mounted at its ends on the transverse bars of the said frameand carrying a cylinder 17, which is provided with any desired number ofradially-extending blades or knives 18, extending longitudinally thereofand secured to its periphery, preferably by means of counter'- sunkbolts. The shaft 16 is formed with a rearward extension 16a, which isprovided with a bevel-pinion 19, meshing with a similar pinion .20 onthe adjacent end of a shaft 21. rlhe other end of the shaft Z1 ispivotally mounted in a side bar of the frame 1. A boxing '.22 is securedon the shaft 21, and to the said boxing there is connected arearwardly-extending lever 23, arranged in convenient relation to thedrivers seat so that by the proper manipulation the shaft Z1 may bemoved so as to carry its pinion 20 into and out of mesh with the pinion19, and thereby start or stop the revolution of the set of knives 18. A.hub of one of the traveling wheels 3 is extended inwardly and isprovided with a sprocket-wheel 25, connected by sprocket-chain to acorresponding wheel 24 on the shaft 21, so that the cylinder 17 and theknives may derive their motion from the main traveling wheels.

The inner frame 14, as best seen in Fig. 4, is V-shaped incross-section, so as to permit the cotton to stand straight where themachine passes over it. At the front end of the main or outside frame 1`Scrapers 26 are mounted 27 designates two plow-beams that are pivotallyconnected at their front ends to the axle 2 and pass rearwardlytherefrom through vloops 28 on the rear cross-bar of the main frame.rlrailing plows 2E) are carried on the rear ends of said beams 27.

In the practical operation of the machine the outer frame travels fromplace to place with the inner frame raised into an in operative positionby means before described. When it is desired to chop the cotton, theinner frame 14 is lowered, which will carry the cylinder 17 and the setof knives 18 into operative position, and then by the manipulation ofthe lever 23 the shafts .21 and 16 may be coupled together to impartmotion from the main wheels 3 to the shafts 16, and colisequentlv alsoto the knives.

l laving thus described the invention, what is claimed as new is l ln amachine et the character described, the crunbination of an outer mainframe provided with traveling wheels, an inner vertically-adjustzibleframe, a lever fulcrumed on the main frame, yokcs and connecting-boainssecured together and to said lever at one side of its fulcruin, andalsosecured to the inner frame whereby the manipulation of the leverwill raise and lower the inner frame, a cylinder mounted in said innerframe and provided with a set ol' radial knives on its pe.- riphery, andmeans for driving said cylinder.

2. A machine of the character described, comprising an outer main frameprovided with traveling wheels, an intermediate transverse beam, aninner vertically-adjustable frame mounted Within the main frame at oneside of said beam7 a standard mounted on said beam, a lever fulerumed on.said standard, transverse yokes secured to the inner frame, a beamconnecting said `vokes and connected to one ond of said lever, guidessecured to the main frame and encircling the ends of said Lvokes,cotton-chopping devices carried by the inner frame, and means foractuating said device.

8. A machine of the character described comprising an outer main frameprovided l with traveling wheels, and an intermediate cross-beam, eninner vertically-a(ljustable frame mounted in the main frame at one sideof said cross-beamI means for raising and lowering the inner frame7 saidmeans includ ing a standard mounted on said cross-beniny and e leverfulcrumed intermediate its ends on said standard, a shaft mountedlongitudinell;r in the inner frame and provided with a rear extensionprojecting into the main frame at the other side of the intermediatecross-beam, cultivating devices carried bv said shaftJ means foractuating said. shaft trein the traveling wheels and e notcheddetent-bar secured to the rear end of the main lrame and designed forengagement with the rear end of the aforesaid ever.

4;. In a machine of the character described the combination of an outerframe, an inner trame mounted therein, a longitudinal cylinder in said.inner frame and provided with a set of radial knives means for rotatingsaid cylinder, Scrapers on the mainframe in front ol said cylinder andtrailing plows Supported by said main frame at the rear of said c vlinder.
